Woodland Interior, Louis Comfort Tiffany
Watercolor and gouache on tan paper, roughly 16×22″ (40x56cm), in the Metropolitan Museum of Art.
James Gurney has a nice post on his blog today about some of his favorite gouache Masters, which prompted me to think of a few artists who did beautiful work in gouache, though they were not particularly known as gouache artists.
This wonderfully realized sketch by Louis Comfort Tiffany (yes, the same Tiffany famous for stained glass) shows off the immediacy of notation that gouache facilitates.
